Application filed March 13, 1917: Serial No. 154,514.

Be it knownthat I', FRANK S. RHoAns, a

-citizen of the United States, residing at Aurora, in thecounty of Kaneand State of Illinois, have invented new and useful I mprovements inUniversal Joints, of which the following isa specification. Y c

This invention -comprehends improvements in universal joints and relatesparticularly to incased joints of this nature having a driving yoke anda driven yoke connected by studs or journals to a ring.

One of the objectsof the invention is to provide a universal joint ofthis typel which is of extremely simple construct-ion, which has nocomplicated parts and which may be and quickly Vassembled anddisassembled. j l

Another vobj ect of the invention islto generally improve universaljoints to render them more practical, useful and commercially desirable.i j;

With these and other objects in view Las will become more apparent asthe description proceeds, the invention consists in .certainnovelfeatures of constructiom'combination 'and arrangement of parts asv-willb e hereinafter fully described, illustrated and claimed.

.In the drawinv s,

through my improved universal joint.

the weakening effect of the entrance slots 22,` l I form the ring withan enlargement 211 op- Referring in detail to the drawings by numerals,1 designates a hub having a peripheral flange 2 on one end thereof whichis bolted or otherwise-secured to a knuckle or yoke generally designated3 having a base plate or disk 4 on -which are formed a pair of arms 5.The hub is connected to a shaft 6.

The" yoke 3 coperatesl with a yoke or knuckle 7 having arms 8 formedintegral with a hub 9. Keys or ribs 10 are formed on the interior of thehub 9 and engage the ribs. or keys 11 on the shaft 12 which'has asliding `movement within 'the hub 9. The arms lof the twofknuckles oryokes extend into a connectingv ring'l land are pivotally connectedthereto. The interior surface-of the ring is formed at four. points withfiat faces for. engagementl with the outer faces of the yoke arms asbest shown The arms 5 of the yoke 8 are connected to the-ring 13 by ahollow pin 14, the ends of which extend through openings in the lringand form journals. .The pin may be closed at its ends by plugs 15 and isformed-with oil passages 16. Oil or Vgrease may lenter the interior ofthe pin 14 through the openings 17. Bushings 18 are carried by therlnggand encircle the terminal portions of the vpin as clearlyshown.y Tolock the pin 'against longitudinal and rotational rnove-A ment, I employa key or lock' pin 19 which may be driven into position through thebaseVplate 4c as'shown in Fig. l1.

i The arms 8 of the yoke 7 are preferably formed with integral studs orjournals 20 which may be'slippedinto position within the sockets oropenings 21 of the ring through the slots 22.-4 -After the journals 20are imposition within the ring openings 21, bushings 23 are driven intoposition and To counteract posite each of the slots as best shown inFig.

ll.- The journals' 20 are formed with oil passages 25 which maybe-closed at their onter ends by plugs=26 and which communi- -cate withthe oil assages 27.

. A `casing or the base-plate 4' of the yoke 3 and Acarries apacking-,strip` 30 which bears tightly against the section 29. This lasti Y Ye Joint' s formediri sec-` tions 28 and2fi'.A The section 28 isboltedV to' mentioned section is heid in engagement o of oil and greasefrom the hub 9, I provideV on .the outer end of this hub, a ring or nut33 which engages a Washer 34 bearing against a packing ring 35.

may be slipped into In Fig. 5 I have illustrated a modified form of myinvention. In this form, a' hub 36 is connected to a yoke 37 having arms38. The yoke 37 coperates With a yoke 39- having arms 40. Each of theyoke arms is formed with an integral journal 4l Which fits Withinanopening 42 in the connecting ring 43. The journals may be slipped intoplace through vslots 44 in the ring and after they have been positioned,they are secured against displacement by bushings 45 of a largerdiameter than the Width of the slots 44. To hold the bushings inposition, I employ a retaining ring 46 which is bolted or otherwisesecured to one side of the connecting ring 43 and Which is formed With acircumferential laterally projecting ange 47 which seatsl inan annulargroove formed'in the periphery of the'ring 43 and in the notches 48formed in the ings adjacent the outer end.

TheI ring, besides retaining the bushings in position, acts .as a forthe* ring 43. I

A casing 49, having the sections 50 and 51 constructed similar to thesections of the first described ca sing, incloses the modified joint andacts as a dust guard and'grease and oil retainer.

Instead of forming the journals integral with the yoke arms, they may beformed separate therefrom and connected thereto as shown inFig. 10. Herethe journal 52 is driven into the arm 53 and is reducedadjacent itsouter end portion `to accommodate abushing 54. The ring 55 is formedWith an opening 56 equal in diameter to the larger diameter of the.journal so that lit position from the eX- terior of the ring.

From the foregoing description taken'in connection With the accompanyingdrawings, it Will be apparentthat I have provided a universal jointwhich is susceptible of various modifications, Which is extremelylsimple and practical, Which'is very eflicient,

1n operation, and which maybe easily assembled and disassembled.

While I have shown and described the vpreferred :embodiments of myinvention,

side of the bush-- reinforcing member it Willbe clearly understood thatI do not Wish to be limited to this construction, but may make suchchanges as will fall Within the scope and spirit4 of the invention asclaimed.

What I claim isz-,- 1. A universal joint including a ring, yokes havingarms extending into said ring,

`the ring being formed lWith journal openings, journals connecting saidarms with the ring the ring having entrance slots to permit the journalsto be engaged with the journal openings, and bushings surrounding thejournals, said bushings being of a larger diameter than the Width of theslots.

2. A universal joint including a connecting ring formed with journalopenings therein, yyoke members having arms extending into said ring,journals formed on the arms of one of said yoke members, the

ring being provided with entrance slots to permit said journals to seatin the journal openings, bushings surrounding the journalsv and a pinconnecting the arms of arms of the other `yoke member with said rings,and means for holding said pin in hosition. y 'i 4. In a universaljoint, a connecting ring, bushings therein, yokes, journals carried bythe yokes and extendi g into said bushings,

and a retaining ring secured to one side of said connecting ring, theretaining -ringbeing formed With. a lateral ange andthe ico bushingsbeingv formed With'notches iii-'one side adjacent `their outer ends toaccommodate said flange.

5. In a universal joint, a connecting ring having openings, yokes,journals on said yokes received Within said 0penings, the

for said journals, ybushings surrounding the journals of. a greaterdiameter than the .Width of s'aid entrance slots and a retaining j ringbeing .also 'provided with entrance slots,
